DUMPING-WAGON.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed July 6, 1903. Renewed February 12, 1904. Serial No. 193,344.

' To all whom, it may cn0e7'n:

Be it known that I, WILLIAM J. JUDD, a citizen of the United States, and a resident of Park Ridge, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention relates to dumping wagons and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

In a dumping wagon it is a decided advantage to have the wagon body set low or near the ground. This allows it to be more readily and easily filled and emptied and its contents tobe inspected. However, when a low wagon body is employed and the bottom boards are separated to swing apart and permit the load to fall out, and the wagon is then moved the bottom boards, if permitted to swing wholly, or partly, beneath the horizontal plane of the bottom of the wagon are apt to strike the load which has been dumped, or some other obstruction, and to become in jured or torn from their fastenings.

It is the purpose of this invention to employ a low bodied wagon with a bottom composed of hinged members so supported that when the bottom boards are separated to permit of the escape of the contents of the wagon, they shall be promptly and automatically moved up out of the way alongside of the outsideof the wagon body. In addition there are added some details of construction and operation.

In the drawings Figure 1 is a top plan view of a wagon body embodying the invention, the supporting chains being shown in dotted outline and the bottom being closed. Fig. 2 is a side elevation of the same showing the bottom open and one of the bottom boards in its highest position, Fig. 3 is a vertical section and partial rear elevation of the same showing the bottom closed, and Fig. 4 is substantially the same view with the bottom open and the bottom boards pulled up out side of the wagon body. Fig. 5 is an enlarged vertical section of part of one side board and part of a bottom board and the lifting chain connections when the bottom is closed. Fig. 6 is a similar view with the bottom board lifted alongside of the wagon body and Fig. 7 is an enlarged transverse vertical section of the lifting chain roller.

In the drawings, 10 is a wagon body (the running gear not being shown) having slop- .ing ends 11 and 12 and vertical sides 13 and 14. The size, shape, style and material of these parts may be varied at pleasure to suit the varied uses to which a dumping wagon may be put.

The bottom of the wagon consists of two longitudinal boards or members 21 and 22, each swung by a flexible link joint from a rod 23 secured in suitable bearings 24 to the sides of the wagon body. Each bottom board is provided with an outwardly and upwardly extending angle iron or pair of angle irons 25, 25 secured to the board by rivets 26, 26 or in any suitable manner. At its upper extremity' each angle iron 25 is pivoted to a link 30 which, in turn, is pivoted to a lever 31 rigidly secured to or made integral with the rod 23 and adapted to swing on the bearings 24, 24 attached to the sides 13 or 14 as the case may be. The lever 31 is provided with an eye 32, or other flexible connection, with a pulley block 33 adapted to receive and to be raised or lowered by a chain one end of which is made fast to the wagon body and the other end of which is adapted to be wound and unwound on the roller 41 and which passes over aguide pulley 34. It will thus be seen that pulling the chain upward from the position shown in Fig. 3 or Fig. 5 to the position shown in Fig. 4 or Fig. 6 will raise the lever 31 on its hinge 23, will carry with it the link 30 and the angle iron 25 and consequently the bottom board 21 or 22 as the case may be, the extent of its upward motion depending upon the size of the parts and their relative positions.

If deemed desirable, each bottom board may be provided with small stiffening angle irons 27 27, longitudinally-placed to make a tight joint with the side boards when the wagon is closed. Each bottom board is also provided externally with a hollow guide tube 28 secured to it by straps 29, 29 or in any other suitable manner and adapted to receive the supporting chains 50, 50. These chains are each secured at one of their ends to some suitable point as 51, 51 at the rear of the wagon body 10 diagonally opposite and above the bottom board which they support. They are each caused'to pass diagonally downward to the opposite side of the wagon body and through the guide 28 longitudinally secured to the bottom board on such opposite side. These chain guides, 28,

28 are preferably made of iron tubing but their exact form is immaterial so long as they perform the function of keeping the chains 50, 50 straight and without kinking or tangling. At either end of each guide is placed a small roller 53 which assists in changing the direction of the chain and reducing the friction at that point. After passing through the guide 28 and over the roller 53 each chain is led to the opposite side of the wagon body and through the pulley block 54 and thence to the roller 41 previously mentioned. Each bottom board is thus supported from the wagon by a supporting chain passing underneath it and which chain is secured to the opposite side of the wagon, the tendency of the two chains being thus to pull in opposite directions toward each other and to close the bottom of the wagon tightly, holding the inner edges of the bottom boards firmly against each other.

The roller 41 is mounted transversely in suitable bearings in the wagon body and near the front of the vehicle so as easily to be controlled by the operator. It is hollow and provided near its center with a stop or plug 42 rigidly secured thereto. To this plug is secured on each side a coiled spring 43 and 44 the other end of each spring being'secured to a bracket 45 fastened to the side 14 of the wagon body. At the outer extremities of the roller beyond the wagon body it is provided with a spool or sleeve 46 adapted to receive the lifting chain 40 and to which the end of this chain is fastened. The supporting chains 50, 50 are secured to the roller within the wagon body between the sides 13 and 14. ithin the wagon body, also the roller is provided with a pawl and ratchet by means of which it may be rotated to wind up the supporting chains 50 and close the bottom of the wagon by drawing the bottom boards 21 and 22 together. The arrangement of the chains 40, 40 and 50, 50 on the roller is such that one is unwound as the other is wound and vice versa.

Each side board 13 or 14 is provided at its lower extremity with a longitudinal scraper 15, consisting of an angle iron or other convenient form whereby as the upper surface of the bottom board is drawn under the edge of the side board and up against it the dirt clinging to it is removed.

The mode of operation of the device is as follows: To close the bottom of the wagon the pawl lever is actuated to rotate the roller 41 and wind up the supporting chains 50, 50. These draw the bottom boards together, the chains 40, 40 unwinding from the roller at the same time. To open the bottom and dump the load the ratchet on the lever is released, the bottom boards separate and are automatically drawn under and up against the outside of the Wagon body through the force of the springs 43, 44 Within the roller which has been wound up as the wagon bottom was closed. The bottom boards are thus out of place and away from the danger ofstriking obstructions of any kind.

It will be seen that my dumping wagon involves among other things two distinguishing and characteristic features of construe tion and operation, in that the means for closing the bottom boards are so arranged as not only to lift the boards and draw them upward, but to draw them toward each other so as to make a tight bottom, and the addi tional weight of the load tends to keep the bottom boards closed, and this is accomplished in the present instance by crossing the supporting chains so that'the stress or strain upon the supporting chains is at a point diagonally opposite the points of the con nections of the chains to the respective bottom boards. In the present instance, as above explained, they are secured at one end on opposite sides of the body and are crossed and operatively connected to the boards which are connected to the opposite sides of the body, and then the chains are again crossed and connected to the means for operating the chains, so that by this diagonal connection and crossed arrangement of the chains the doors are' held in closed position and the strain tends to draw and hold the adjacent edges of the opposite doors together. This is a novel and important feature of applicants invention and may be accomplished by modifying the details of construction and arrangement of the parts without departing from the spirit of the invention, the arrangement shown being found satisfactory in operation. Furthermore, means are provided for positively operating the'doors both in closing them and in opening them, and in the construction shown there are two sets of chains, one set oiorating to positively close the doors and tie other set to positively open the doors, and in the specific construction shown these are interdependent and are arranged so as to operate simultaneously in the manner set forth.

What I claim as new is:
